Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021658, here are decompositions:

7 + 1021651 = 1021658
31 + 1021627 = 1021658
37 + 1021621 = 1021658
97 + 1021561 = 1021658
229 + 1021429 = 1021658
241 + 1021417 = 1021658
271 + 1021387 = 1021658
277 + 1021381 = 1021658

Showing the first eight; more decompositions exist.
